My understanding is that most Communistic regimes were explicitly Atheist. I'm not a historian so I may not have my facts completely correct, but my understanding is that: The Soviet Union more or less outlawed religion. China is officially Atheistic but tolerates certain recognized religions. My understanding is that they outlaw/suppress certain things they view as "superstition" (such as supernatural and moral aspects of Qigong) in a way that would be considered questionable in the west. On a more positive side, I wonder if there are any of the Scandinavian countries that could be considered to more or less implement Humanism. I say that because it seems like Humanism fills a lot of the same roles for Atheists (moral system, providing hope, providing meaning etc.) that religion does for theists.
